The MacApper weblog details how to take advantage of Automator to create a very simple version control system when you need a good versioning solution but a full-on version control system, like previously mentioned Subversion, would be out-and-out overkill.

The backup methods used are very similar to my simple version control system for Windows, but this Mac solution takes advantage of the much-maligned/beloved Automator. Not only is this a useful versioning method, but the post also serves as a nice introduction to Automator.
